Abstract

The invention discloses a method for mechanochemical coupling ultrasonic chemical strengthening of metal leaching in secondary zinc oxide powder, comprising: mechanical activation: mechanically activating raw materials containing secondary zinc oxide powder to obtain an activation material; ultrasonic treatment: combining the activation material with the The acidic leaching solution is mixed to obtain a mixture, and the mixture is subjected to ultrasonic treatment, and the obtained liquid phase is the leachate. The combination of mechanochemical activation and sonochemistry enhanced the leaching rate and leaching rate of multi-metals through structural destruction and cavitation of secondary zinc oxide powder. This process can indirectly reduce the use concentration of acidic leaching solution and shorten the leaching time. In actual production, the specific application of this process can reduce the anti-corrosion cost and operating production cost of reaction equipment, and indirectly produce good production benefits.

Description

technical field

[0001] The invention relates to the technical field of industrial solid waste treatment and resource utilization, in particular to a method for mechanochemical coupling ultrasonic chemical strengthening of metal leaching from secondary zinc oxide powder. Background technique

[0002] In the process of blast furnace iron and steel smelting, metal impurities such as zinc and lead contained in iron ore are reduced by reducing agents such as coke under high temperature conditions to form saturated steam of simple metals, fine dust such as iron ore, coke and high-temperature auxiliary flux , was carried out of the furnace by blast furnace gas, and became the main solid waste of the iron and steel industry: blast furnace ironmaking fumes (gas ash or gas mud). The iron and steel output of my country's iron and steel smelting plants is increasing day by day, which promotes the take-off of my country's economy, but on the other hand, these industrial solid wastes prod...
